When collecting data during a live incident, which data type should be prioritized due to volatility?

• A. Hard disk images
• B. Email archives
• C. Network logs stored remotely
• D. RAM contents (volatile data)

Answer: (D)

When collecting data during a live incident, you prioritize volatile data—what’s currently in RAM. RAM contents are lost as soon as power is removed, so capturing them right away preserves memory-resident information such as running processes, loaded modules, active network connections, opened files, and in some cases credentials or encryption keys kept in memory. This snapshot helps you understand what the attacker did, what malware is doing in memory, and how the system state evolved in real time. Hard disk images, email archives, and remotely stored network logs are valuable, but they are non-volatile and can be collected after you’ve preserved the volatile evidence. They won’t vanish immediately when the incident occurs, so they’re important to gather as follow-up, once memory has been captured.
